I have a question about the pressure used in the "forces" function in the controlDict file.

My case is a cylinder floating in a tank of water. The free surface is still, there is no incident wave. At t=0, I raise the cylinder of x centimeters (vertically) and then I let it go. I look at the free decay oscillations of the body and I would like to monitor the heave radiation forces.

- if I put "p" for pName, does this mean that I will have the force from the total pressure?
- if I put "p_rgh", does this mean that I will have the hydrodynamic force (from the dynamic pressure)?
- and if I put "p_rgh", does this lead to the correct viscous force?
